# Libva-utils Project
libva-utils is a collection of utilities and examples to exercise VA-API in accordance with the libva project. --enable-tests (default = no) provides a suite of unit-tests based on Google Test Framework. A driver implementation is necessary to properly operate.
VA-API is an open-source library and API specification, which provides access to graphics hardware acceleration capabilities
for video processing. It consists of a main library and driver-specific acceleration backends for each supported hardware vendor.
If you would like to contribute to libva, check our [Contributing guide](https://github.com/intel/libva-utils/blob/master/CONTRIBUTING.md).
We also recommend taking a look at the ['janitorial' bugs](https://github.com/intel/libva-utils/issues?q=is%3Aopen+is%3Aissue+label%3AJanitorial) in our list of open issues as these bugs can be solved without an extensive knowledge of libva-utils.
We would love to help you start contributing!
The libva-utils development team can be reached via github issues.
